T 0 all whom n/nay con-clem.' y

Be it knownthat IQIIOWARD K., KING, a

citizen of the United States, residing at Philadelphia7 inthe county of Philadelphia, Stateof Pennsylvania,have invented afnew and useful Improvement in Sheet-Registering Devices, of which the following` is a movement.` n.

The invention comprises improved means l Vso specification. v l y n.

The invention relates to sheet registering device for sheet feeding machines, andi is particularly applicable to continuous press feeders. 1Tlie'object is to provide improved means for bringing the sheet to proper'position or register before its gdelivery. 1

Y The invention comprises improved'nieans j for moving'the sheet transversely its direc tion of delivery tol or against a stop. or gage adjustably positionedl to ,limitv its' sidewise for actuating the sheet either to the right or to the left as required, including a reversible actuatingmechanism adapted to cha-nge the initial movement of the gripper supporting means, for right or leftlia-ndguide as desired; means for adjusting the position ofthe actuating device, improvedmeans for both preliminary and for: final adjustment of the position of thestopor gage; means for `rendering inactive the side guide-mechanism on one side of the machine7 while rendering activethe side guide mechanism on the other side,'.and1vice versayimproved adjustable frictionalV means for maintaining the side guide actuating mechanism in desired opera-f tive position, but adapted automatically to assume another position of adjustment when required by the position ofthe stop or gage, andmeans forarbitrarily changing the tension "of the frictional means either to render its normal operation'eifective, without preventing its automatic adjustment, or for renderingl the actuating vmechanism rconnected therewith ineffective, whenit is desired to put said side-guide out of commission.

l The 'invention also comprises means for producing a curve in the plane of the sheet on the line of itsengagement with the stop or f gage to render it more rigid and'prevent it.y

from crumpliiig when pulled against the stop;

Referring to the drawings, which illus.L trate merely by way 4o-fexam'ple suitable means for the embodiment yof my invenv Fig. l is a side elevation of part of a'sheet rand stop mechanism. Y

Similar numerals refer .to similarY parts throughout the severalviews.

By way of example I have shown my improved mechanism as; applied toiV a sheet feeding machine for rotary printing presses; the framex20 and table 2l supports the us` ualk delivery apron V25, from which the sheets are delivered Vto the press roller 22 of the printing press. f'

In order to secure the proper guiding of thesheets so that they will register, I have provided improved mechanism for the side guiding of 'the sheets in order to bring them A into position for delivery to the press. This comprisesbroadly a suitable adjustable side stop or gage mechanism` supported in the tion therefore or'v one gege `:rnd gripper mechanism willsut'ice iorboth.

i Gage mechanism.

The ynormally stationary nicchmisni vcon'iprises thebody 29, adjustsbly secured upon the rod 30, which is supported in the frame 23. This bodV 29S is mounted on 'the ber 30, which" is normally r1`-ststionary, and has preliminary adjustment .thereon by ineansof the it llowine; ineclninisni. The bar is held in reasonably tight engagement with the traine 23- by ineens oit the plate 31, engaging the flat surface 32 ot'said frame 23. The eiiiciency of engagement between plate and traine is'finsintained by the clamp screw 33, see Fig.' 16. This also prevents the, turning of the bar 3()k in the freine 23. The body 29 is secured inv position on the-ber 80 by means: of the vset-screw The grsdnstionsor marks 35 on bar 30, correspond to the sizes ot the sheets'to be operated upon, fend servelto secure tlie proper position of initial or preliminary `adjustment. Bot-h ends of the bar are provided with these grraduations.A ri further means for adjustment, in Iorder-to secure' exact refry istration, consists in providing the adjust-- ing screwY 36,; threaded into` the end et' har 30as shown'in Fig; l5. VThis adjusting screw 36 has e swivelinp,` engagement with the frame 23 and is operated menu-ally by means ot1 the lrnurled .head .Y

The body or formation 29, as shownin Figs. 7 to l1, inclusive, comprises the src shaped or convex upper surface 38, having the channel '39 extending ytrnnsversely the delivery movement ot the sheet.: Near the rear end oil channel 39, andl flanking the same, are the upwardly, projecting stops or gages 40. 'Formation 29: isnlso provided with the upwardly extending arm to the rear of the gages or stops 40.

Gripper mechanism.

Tn frame 24 is slidsbly secured the bsr n 42, as shown in Fig. This vber 42 is On ber 42 isadjustablymounted the'body ord-formation 44. The position of adjustment is secured in the following way: Through the'top of the body 44 are proy vided the holes 45 in which ere .seated 'the Y tion of plate 49 projects the tension screw 5l, threaded into the` body portion 44,having a flange for engaging 'the plate 49a-i'id provided withthe knurled head Tt will thus bessen that when the screws 48 are properly adjusted to eiert pressure on ber 42 through the washers '46, this pressure becomes effective by .screwing down the screw 5l; end thus the body44'fs normally held in the desired position or' .adjustment onthe bar 42.

It will be untlerstood--tliet when the screws '48 erejproperly ad'justetb such adjustment becomes effective by'tighteningr the clampk plate 49 by ineens oi the screw 51, and thus thedesired frictional eng-agement or member 46 on bar 42 is secured. By

releasing` the pressure oi" platev 49 by partiallyk withdrawing clamp screw 51,' this 'frictiona-l ense-gement becomes ineffective.

Thebody or member 44v is provided with the vdownw'ardly extending` arm 53, having et its lower end the horizontally extending gripper-jew member 54. This jew member 54 yis slidablyY seated in the channel 39 of member' 29. `Tn the lower rend of erm 53 is pivetal'ly secured, as at155,the plate 5,6. To thisiplste is secured the upper gripper jawV member 57, `and also the .two flanking *fingers 58, see-Fie. 14. A- post 59V is also securedto thexpi oted plate' 56, and at the upper end of the plate 56 VVis secured 'the pivoted hook 6G for engaging' theend of tension spring 6l. The other end of sprinpT 6l is secured? to the bent-over end G2 vof rod 3, slidebly supported in the lug 64 ot body or member 44. This rod 63 is held in position of adjustment by the knurled-headed nut 66, threaded on said rod 63, (see Figs, 2 and "r'to l0 ine). l

VVhenit is desired to hold a gripper out of action,'the tension on plate 49 is relieved and the upper end 67 or' armv 4l ot body or meinber29, isi brought over into engagement wi'thlug Ot body'44;'these two ele ments 65 and 67 are thensecured and held together byany suitable Ineens, es itorvr example, by thesprine'clip 68, Vsee Figs. 2 s'nd 17. At the saine time, the engagement oi post 59 with arm 4l, serves, when the parts are, in this position, to holdgthe 'gripper jaw member 57 and the flanking ngersv in the open-Vposi'tiomto permit the sheet to travel beneath them. j i

Aol/uniting mechanism for 'the vWippe? jaws. As above stated, the body portion. 44, to

which aresecured the gripper jaws v 4 and V57, is held in trietionalengagement With Vbar 42, so that normally they body 44W1llV move ed into link 7 6 piv'otally connected to slide block72 by ithe pivot bolt 77, which 'is' also connected to the rack bar 7l. and block 72 are held in slidable engagement with the Vtable 7 3 by means of the clamp plate v78.

rlhe other end or connecting rod 74vis secured, through lthe rock lever 79 and link V8G, tothe lever Sl, pivotally mounted atl 82,

and provided with the roller` 83 adapted to Vi-ngage the cam 84, Vhaving properisynchrof nous rotation with thek other operations of the machine. lThe rotatingof the cam y84 givest-he required yreciprocating` movement of rod 74 and, consequently, ot rackbar 7l and pinion 70, and consequently the proper or Vrecuired reciprocating` movement ot bar 42 and the gripper mechanism carried thereon grthe cam 84 being so ,formed as to Ysecure the required reciprocating movements of the gripper mechanism. That is, to pnll the sheet at -a moderate speed, dwelling out `until the sheet has passed out ,of the way, and then moving in quickly before the next sheet reaches the guide. 4 l

lt will be noted lthat `as shown in Fig. 5, the rack bar 7l is on one side of pinion 70, ivhile as shown in Fig. 6, the rackbar is in cooperation with the vother vside of the pinion. y 7

rlhe ineanstor making it possible to shift or carry the rack barfroni one side orc the pinion to the other, co nprise the threaded connection at 7 5, and the block 7 8 provided with the flange 85k removablyy secured to either post 86 or 87 by the Cotter 88. That is toy say, starting with the parte as sho'ivn in Fig. 5.y in order to-change the posi-tion shown in Fig. 6, it is only necessary to withdraw lthe ootter 88 'from post 86, then ref. inovegthe block 78 from post 86, litt the' slide block 72`irom table 7,3, and turn it over, so as to bring the rackbar 7l from Pinion also cooperates The bar 7l pers and its cooperating stop or are moved out of the Way orpath ot travel `of the sheet, and the gripper mechanism is thebar 42 as alreadyr described.

position shown inFig. 5, to positionshowii -in 6.l `The rack bar is *then secured 'in its new position by placing4 the block `78 onpost 87 Vand inserting theA cotter 88 inplace as shown, see Figs. 6 and 6. The thread on connecting rod 74, asiat is so ne that a halt turn of link 7 6 ivithblook 72, which is allthat is required., does not substantially alfect the required effective length of rod 74.`

The object of transferring the rack bar 7l from one side of the pinion 70 to ther other,

,and viceV versa, is toV secure the properfinitial actuation oit the gripper element, relatively t0 the cycle :of operation of the inachine, depending upon Whether the right- Vhand gripper or the left hand gripper is to beused.y In otherwords, the forwardA movement for one gripper Would be, in direction, the reverse of the forwardLinove-` ment of the other gripper; obviously therefore, the ydirection 'of initial Aiovementl oi bar 42k, Will depend upon` which side kopinion 7,0 'the rack bar is in cooperation during its initial movement. Then it is desired to bring one gripper into operation and put the other out ot .commission7 it is only necessary toy etliectl kthe frictionall cooperationy of the gripper bodies on bar 42 as above described, and then Vturn the rack'bar 71 over lfrom one side of the pinion 70 to the-other, as' described, Without disturbing anyk other parts of the machine. n' Y u The rackbar 7l is placed on the right side of the pinion 70 when Working the right hand gripper and on the lett side of .the pinionwhen rv'orking'theleft hand gripper.

V. Q-age, in order to secure its proper register. Depending upon 'whether it 'is to oc pulled .A to the right or to the left, one o'i".tlie.grip-l gage device released from its inrictional cooperation with Theother gage device is secured to the bar 30 in approximately proper positionv with regard to the size of the sheet to be operated upon. The graduations 85 on saidv bar are utilized yin this connection. fAn" additional and final adjustment of the `stopmember 2Qy is secured bythe adjusting screw 35, so that, by a few tests, `the exact register of the delire ered sheetl is secured. A further graduation is preferably provided on the tace of a part ot frame 23 surroundingscrew 36 and adjacent knurled-head'37, as shownin Fig. 4. The gripper member 44 is then adjusted approximately, by means ot the iirictioiial engegeirent above described, tothe bar 42. The actuation of ber 4t2, in 4'he manner above described, causes the required reciprocating movement of the gripper j aws.

Taking for the arrangement shown in Figs, 2, 7 und l0, with the gripper and stop o1 mechanisms, on the vright beingused, it will be noted that the body ed is provided with the tivo downimrdly' projecting` lues 64; end.V 65, und that the inember 29 has the upr-:srdiy project-nig` lug` 67 -which projects beti'veenlugs Gfi and 35 and in their line' of travel. it oliows that if, Curing; the reciprocation of ber d2, there should bc a i'endency ot body te to trsvel in either direction beyond s required distance rciutireiy to member Q9, the projection 67 Wili engage' either abutment. or (35 and stop the "further lnim-:ement of 44e; that is, the frictionoi nent between and bur i2 is s ne member .vill noruii Vstroke of' the ber, in either l n unobstr rete-d, but will permit the tra vvel' of the bei' l2 b'ef'ond its movement in either r b ti' iu` 2 gage with the stop Y lt Wille-dsc be noted that when the body ist is in the position shown in '7., the aw 57 is in the closed position cooperating with the jew member 54. X"Vhen hoivever the body le moves to the forward position that is to the lett, as shown in 10, the. post 59 on plate 56 engages the arm or projection el. ot' body 29 eno causes the actuation or plate 56 und the correspondingsctuation and lifting oit jew member 57 andthe tieni-Q ing lingers 5S into the open position,l s s shown insaidFig. 10.- Immedistely however upon movement of body 4A to the right7 the jew member 57, in response to the tension or spring;` 6l, oves toward the closed position, and finally, into the closed posi* Vtion es soon as post 59 leaves the abutment on arm 4:1; so that, in the movement oit the gripper jews toward the lett into the path i of tre-vel of the sheet, the jaws src forced open by the engagement of post 59 4Vwith abutment on di, und in the movement to the right oit member :2Qa the jaw m moers iminedicteiy begin to ciose und inally do close in time to the sheet and puii it over tothe stops or Q;es e0. before the end ot said movement to the right. is kbrought into engagement with the stops 40, the further movement or the jews results in aslipping of the jaws from the sheet until they nallypass beyond the margin thereof. The proper trictionel engagement of the jews, suicent to move the sheet to the stops, und yet permitting the release of the sheet otter it reaches the stops, is secured by the adjustment of the tension ot' the spring` l by operation oi the l-nurledheaded nut.

in order to prei'ent crumpling or buck` .2.. n .1 elle; ine sheet ling of the sheet after it has engaged the stops or gagest), due to the pull 'of the gripper jews, I have tound thet'the most effective Way is to form the portions of the edges ofthe sheet7 which engage the stop members 4:0, into curved lines and the parts adj scent thereto into correspondingly curved planes. This is accomplished by providi'n'g the upper surface, as at 3S, of the member 29 in a curved or convex 'formation' end then pressing the sheet down on both sides of the jaws by means of the fingers 58, which close upon the sheet' simi'ilteneo'usly with the closing of the jews. it insles'practicolly no dii'lerence what the' formation or the sheet edge isbet reen the aws,` but the important thing is that the edges Which en* tige the faces' or the'stops or geg-es 40 sno ld have a curved extension so asA to s i i het part of the sheet in the lines of said engagement, on both sides otthe'jaws,
